Abstract: The influence of different concentrations of NaCl, Na2SO4, NaHCO3 and Na2CO3 salts on the ability of growth and development of barley seeds (Hordeum vulgaris) and the influence of these concentrations on the dynamics of activity of NADP enzymes formed in plant cells such as glucose-6-phosphate dehydrogenase (G6PD, EC 1.1.1.49) anddecarboxylatingmalate dehydrogenase (MDH, EC 1.1.1.40). Solutions of Na salts had a negative effect on the growing ability and development of sprouts and the effectiveness of this effect,being directly dependent from the concentration of saline solution This action was sharply manifested at the first stages of seed germination. At the initial stages of development, the G6PD-enzyme showed great activity and the activity of the MDH-enzyme became higher in comparison with the previous one. The salt factor manifested at lower salt concentrations, led to induction of both enzymes, sproutsdevelopmen and associated compared with the previous one. The effect of salt solutions led to a decrease the activity of G6PD / MDH respectively.
